Popis: | Chemical, microbiological and sensorial properties were investigated depending on the storage time to understand the impacts of gamma irradiation at doses of 4 and 5 kGy on frog legs (Rana esculenta) during storage at 2 °C. While TVB-N values of control groups found as 50.11 mg/100 g after a 10 day storage period, 4 and 5 kGy frog legs were found as 48.08 and 43.29 mg/100 g respectively after 17 days. TBA values for irradiated frog legs were observed to be higher at the end of their storage periods. Salmonella was totally eliminated by 4 kGy irradiation. A total of seven biogenic amines; putrescine, cadaverine, spermidine, spermine, histamine, serotonin and agmatine were recorded in frog legs. Ammonia, putrescine, cadaverine and agmatine contents of non-irradiated group were significantly increase during storage period. Other microbiological analysis showed that irradiation at 5 kGy was the best at eliminating bacteria. Consequently, the treatment of irradiation as a preservation method was found to prolong the shelf life of frog legs 7 days longer than the usual methods in cold storage. © 2018 Elsevier Ltd |
